[Embodiment]
A wildlife protection device according to an embodiment of the present invention will be described below. FIG. 1 is a diagram showing the configuration of a wildlife protection device 1 according to an embodiment.

The wildlife countermeasure device 1 is composed of a display device 11, a camera 12, a speaker 13, and a microphone . The display device 11 uses a transmissive LED display device in this embodiment.

The display device 11 is composed of a frame 111 and a blind portion 112 . The frame 111 has an opening A on the inner peripheral side. The blind part 112 is an elongated plate-like member, and a plurality of the blind parts 112 are attached at equal intervals in the entire opening A so as to span both ends of the frame 111 . In FIG. 1, the blind portion 112 is omitted from the position marked with A, and the blind portion 112 is actually attached to this portion in the same manner as the other portions.

A plurality of LEDs are arranged in high density along the longitudinal direction of each of the blind portions 112 . By lighting these LEDs, an image is displayed in the opening A portion in the frame 111 . Since gaps are provided between the adjacent blinds 112, these gaps are open in the front and rear, allowing light to pass therethrough. Since the blind portions 112 adjacent to each other are configured to have a gap, the light transmittance is high, and the image formed by the LEDs can be visually recognized realistically.

In addition, since the gap between the adjacent blinds 112 is open in the front and rear, the display device 11 has good ventilation and can be used without being damaged even if it is installed in a strong wind environment. Installation in a place where there is a high possibility of becoming a strong wind environment includes installation on a power transmission tower, which will be described later, and installation on farmland at high altitude.

The camera 12 is installed so as to be able to capture an image of the front side of the display device 11 (the side in which the displayed image can be viewed). The speaker 13 is installed so as to be able to output sound mainly toward the front side of the display device 11 . The microphone 14 is installed so as to be able to collect sound mainly from the front side of the display device 11 .

The frame 111 of the display device 11 is provided with a control device, which will be described later, and an LED control section that controls the LEDs arranged side by side in the blind section 112 . The camera 12, the speaker 13, and the microphone 14 each transmit or receive image data, audio data, etc. to and from the control device. Therefore, wired or wireless communication connection is possible with the control unit provided in the display device 11 .

FIG. 2 is a block diagram showing the hardware configuration of the control system of the wildlife protection device 1. As shown in FIG. The control device 21 is provided in the frame 111 of the display device 11 in this embodiment. The control device 2 is a computer having a processor 211 , a memory 212 and an input/output interface 213 . These structures are communicatively connected to each other, for example by a bus.

The processor 211 controls each part of the wildlife protection apparatus 1 by reading and executing a computer program (hereinafter simply referred to as a program) stored in the memory 212 . The processor 211 is, for example, a CPU (Central Processing Unit).

The memory 212 is storage means for storing an operating system, various programs, data, etc. to be read by the processor 211 . The memory 212 has RAM (Random Access Memory) and ROM (Read Only Memory). Note that memory 212 may include a solid state drive, hard disk drive, or the like.
The input/output interface 213 is a communication circuit that connects the processor 211 to the display device 11, the camera 12, the speaker 13, and the microphone 14 in a wired or wireless manner.

The display device 11 has an LED section 113 including a plurality of LEDs arranged side by side in a blind section 112 and an LED control section 115 that controls the LED section 113 . The LED control unit 115 communicates with the input/output interface 213 of the control device 21 and controls the LED unit 113 . Then, the LED control unit 115 performs lighting control of each LED of the LED unit 113 and generates a moving image by lighting of each LED of the LED unit 113 provided in the blind unit 112 .

The camera 12 is capable of capturing a moving image around the front of the display device 11 , and image data of the captured image is transmitted to the input/output interface 213 of the control device 21 . The speaker 13 receives audio data generated by the control device 21 via the input/output interface 213 and outputs audio based on the input audio data. The microphone 14 can input sound from around the display device 11 , and audio data of the input sound is transmitted to the input/output interface 213 of the control device 21 .

FIG. 3 is a block diagram showing the functional configuration of the wildlife protection device 1. As shown in FIG. The processor 211 executes the programs stored in the memory 212 to control the image acquisition unit 251, the sound acquisition unit 252, the detection unit 253, the image generation unit 254, the sound generation unit 255, and the output control unit. 256 and a storage unit 257 .

The image acquisition unit 251 acquires image data representing an image captured by the camera 12 . The image data may be still images or moving images. The voice acquisition unit 252 acquires voice data representing voice collected by the microphone 14 . The detection unit 253 is implemented by an image processor and an audio processor, and detects the presence of birds and animals based on at least one of image data and audio data acquired from the camera 12 and the microphone 14 . Furthermore, when the presence of a bird or animal is detected, the detection unit 253 identifies the type of the bird or animal, and determines whether or not the bird or animal is harmful.
It should be noted that the type does not need to refer to an academically accurate classification. Also, in identifying the species of birds and animals, it is not always necessary to specify an academically accurate classification, but at least whether or not the birds and animals are harmful, in other words, an attempt is made to drive away the birds and animals by activating the wildlife countermeasure device 1. It suffices if it can be determined whether it is a bird or beast that should be treated or if it is not necessary. For example, if natural enemies differ between adults and juveniles in a species, adults and juveniles may be set as different species.
The information stored in the storage unit 257 is referenced as necessary for determination of the presence or absence of birds and animals and identification of the types of birds and animals. Specifically, the type of bird or animal is determined using an existing pattern patching technique for images and sounds, and images associated with the type are extracted from the storage unit 257 . Alternatively, a machine learning technique may be used to generate an optimal image for judging the species of birds and animals and avoiding the identified birds and animals.
Also, the specified type and the generated image or sound do not necessarily have to be associated one-to-one. For example, a plurality of image and sound patterns may be required for a certain type, and the image and sound patterns may be selected at random. By doing so, it is possible to reduce the possibility that birds and animals become accustomed to avoidance images and avoidance sounds.

The image generating unit 254 generates an image that the harmful birds and animals whose presence has been identified by the detecting unit 253 evade. Specifically, the image generation unit 254 generates an image of an animal that the bird or animal avoids, for example, an animal that is a natural enemy of the bird or animal. The generated image may be a still image or a moving image.
The voice generation unit 255 generates a voice that makes the harmful birds and animals whose presence is identified by the detection unit 253 avoid. Specifically, the sound generation unit 255 generates sound (crying, etc.) emitted by an animal that the bird or animal avoids, for example, an animal that is a natural enemy of the bird or animal.

The output control unit 256 controls outputting the moving image of the animal generated by the image generating unit 254 and the sound generated by the animal by the sound generating unit 255 to the display device 11 and the speaker 13 in cooperation with each other. That is, the output timing of the image data and the sound data is controlled so that the sound emitted by the animal is output from the speaker 13 in synchronization with the moving image of the animal displayed on the display device 11 .

The storage unit 257 stores a database that stores information on birds and animals. The database stores data necessary for detection of birds and animals by the detection unit 253 and determination of whether or not the birds and animals are harmful. The database also stores image data necessary for the image generating unit 254 to generate moving images of animals, and audio data necessary for the audio generating unit 255 to generate animal sounds.

Specifically, in the database of the storage unit 257, data records are formed for each of the plurality of birds and animals. Each data record contains the type (name) of a bird or animal, whether or not it is harmful to a bird or animal, the outline of the bird or animal, the image data indicating its color, the sound data of the voice emitted by the bird or animal, the animal name of the natural enemy of the bird or animal, the shape of the animal of the natural enemy of the bird or animal. Data of items such as image data indicating the position and audio data of sounds emitted by animals, which are natural enemies of birds and beasts, are stored.

FIG. 4 is a diagram showing an installation example of the wildlife protection device 1. As shown in FIG. Crows sometimes build their nests on pylons used to support power lines and antennas. If a nest is built at a high position on a steel tower, it costs a lot of labor and other costs to remove it. Therefore, it is effective to install the bird and animal countermeasure device 1 in order to drive away the crows gathering on the steel tower.

FIG. 4 shows an example in which the display device 11 of the wildlife countermeasure device 1 is installed on a steel tower 31 . The steel tower 31 is configured by an iron frame structure. Positions D1 to D6 on the steel tower 31 indicate positions where crows tend to nest. Nests are likely to be formed at positions where vertical and horizontal frameworks intersect, such as positions D1 to D6.

The wildlife protection device 1 is preferably installed near such positions D1 to D6. The display device 11 is installed via a display device support portion 118 attached to the frame structure of the steel tower 31 . In FIG. 4, one end side of the display device support portion 118 is fixed to the frame structure of the steel tower 31 and extends downward, and the frame body 111 of the display device 11 is fixed to the other end side. The method of fixing the display device is not limited to this, and the display device support portion 118 may extend in other directions (upward or lateral direction). Alternatively, the frame 111 of the display device 11 may be directly fixed to the frame structure of the steel tower 31 .

4, only the display device 11 of the wildlife protection device 1 is illustrated, and the illustration of the camera 12, the speaker 13, and the microphone 14 is omitted. Since the camera 12, the speaker 13, and the microphone 14 require a smaller installation space than the display device 11, they can be installed at positions near the display device 11 as appropriate. In FIG. 4, three display devices 11 are installed at different positions in the height direction.

FIG. 5 is a diagram showing the flow of processing in the control device 21. As shown in FIG. The processing described below operates by processor 211 of control device 21 executing a program stored in memory 212 .

When the program is started, the processor 211 repeatedly executes processing based on the flowchart shown in FIG. 5, for example, at predetermined time intervals.
First, the image acquisition unit 251 of the control device 21 acquires image data transmitted from the camera 12 . Also, the voice acquisition unit 252 acquires voice data transmitted from the microphone 14 (step S501).

Subsequently, the detection unit 253 performs processing for detecting the presence of birds and animals based on the acquired image data and audio data (step S502). First, the detection unit 253 detects an image of a bird or animal appearing in the image indicated by the acquired image data. For the detection of the images of birds and beasts, for example, first, the image acquired this time from the camera 12 is compared with the image acquired last time.

Of the objects appearing in the image acquired this time, objects not appearing in the image acquired last time are taken as image candidates for birds and beasts. In addition, among objects appearing in both the image obtained this time and the image obtained last time, objects whose positions in the images have changed are taken as image candidates of birds and beasts. That is, these objects are objects that have moved from outside the field of view of the camera 12, or objects that have moved within the field of view, and may be animals.

Subsequently, the detection unit 253 compares the bird and animal image candidate with each of the plurality of bird and animal images stored in the database of the storage unit 257 . Among the images of birds and animals stored in the database of the storage unit 257, if there is an image whose outer shape and color match with a candidate image of a bird or animal is equal to or greater than a predetermined value, the candidate image of the bird or animal is a candidate image of a bird or animal. Judge that it is an image.

Subsequently, the detection unit 253 extracts the recorded voice portion from the acquired voice data. The extracted voice part is compared with the voice data of the voices of birds and animals stored in the database of the storage unit 257 . Among the extracted voice parts, if there is a voice part whose degree of matching with the voice data stored in the database of the storage unit 257 is equal to or greater than a predetermined value, the voice part is determined to be the voice uttered by a bird or beast. .

If it is determined that the image candidate of a bird or animal is an image of a bird or animal, or if it is determined that the extracted voice portion is a voice uttered by a bird or animal (step S503: YES), the detection unit 253 determines that it is an image of a bird or animal. The type of bird or animal indicated by the captured image or the voice portion determined to be the sound emitted by the bird or animal is identified, and it is determined whether or not the bird or animal is harmful (step S504). This identification and judgment can be performed by referring to the data of each bird and animal stored in the database of the storage unit 257 .

The detection unit 253 selects a bird/animal image from the database of the storage unit 257 based on a bird/animal image whose degree of matching with an image (detected wildlife image) determined to be a bird/animal image is equal to or greater than a predetermined value. It is possible to read information on the type and whether the bird or animal is harmful or not. Further, the detection unit 253 detects the voice data of the birds and beasts whose degree of matching with the voice portion (detected bird and beast voice) determined to be the voice uttered by the birds and beasts is equal to or greater than a predetermined value. , it is possible to read out information about the kind of the bird and whether the bird is harmful or not.

When the detection unit 253 determines that the detected bird/animal image or bird/animal sound is a harmful bird/animal (step S504: YES), it compares it with the previous detection result of the bird/animal image (step S505). As described above, the detection of wildlife images is repeated at predetermined time intervals, so it is determined whether or not the same type of wildlife was detected in the previous detection. Since the information on the detection result is stored in the storage unit 257, the previous detection result can be referred to.

If wildlife is detected from both image data and audio data, and the type of wildlife indicated by the detected wildlife image and the type of wildlife indicated by the detected wildlife audio are different, only one of them is If it is determined to be a harmful bird or animal, then the harmful bird or animal should be treated. If both are determined to be harmful birds and animals, processing may be performed according to a predetermined order of priority (such as giving priority to processing of birds and animals having a high degree of harmfulness).

In the previous detection, if the same type of wildlife as this time was not detected last time (step S505: NO, that is, if no wildlife was detected last time, or if a different wildlife was detected last time) the image generation unit 254 generates an image of an animal that is a natural enemy of the bird or animal detected this time. In addition, the voice generation unit 255 generates voices uttered by animals that are natural enemies of the birds and beasts detected this time (step S506). Images and sounds can be generated by reading image data and sound data of the corresponding birds and animals from the database of the storage unit 257 based on the detected and specified types of birds and animals.

The image generator 254 outputs the generated image data (preferably a moving image) to the output controller 256 . The sound generation unit 255 outputs the generated sound data (for example, sounds of barks emitted by predatory animals) to the output control unit 256 . The output control unit 256 outputs the image data to the display device 11 and the audio data to the speaker 13 by linking the moving image indicated by the image data and the cry indicated by the audio data (step S507). That is, the output control unit 256 outputs the image data to the display device 11 and outputs the audio data to the speaker 13 in such a timing that the bark is output in conjunction with the movement of the natural enemy animal in the moving image. (Step S508).

In step S505, if the same kind of wildlife as this time was also detected last time (step S505: YES), the output control unit 256 continues to output image data and audio data to the display device 11 and speaker 13. (step S508). If the same kind of birds and beasts as this time were also detected last time, the processing of outputting the image data and audio data of animals that are natural enemies of the detected birds and beasts to the display device 11 and the speaker 13 is started in the previous processing. Therefore, the output control unit 256 should continue the processing.

In step S503, if the detection unit 253 determines that the wildlife image candidate is not a wildlife image (step S503: NO), or in step S504, the detection unit 253 determines that the detected wildlife image is not a harmful wildlife image. If determined (step S504: NO), the output control unit 256 determines whether image data and audio data are being output to the display device 11 and the speaker 13 (step S509).

If the output control unit 256 is not outputting image data or audio data (step S509: NO), it means that neither the current process nor the previous process detected a bird or beast, and the output control unit 256 is not operated. exit.

If the output control unit 256 is outputting image data and audio data (step S509: YES), birds and animals were detected in the previous process, and the output control unit 256 outputs image data and audio data to the display device 11 and the speaker 13. It is considered that audio data is being output. Since no bird or animal was detected this time, it is determined that the previously detected bird or animal has left, and the output of image data and audio data from the output control unit 256 is stopped, and the process ends (step S510).

6 and 7 are diagrams for explaining detection processing and image generation processing using images in the control device 21 of the wildlife protection device 1. FIG. FIGS. 6A and 7A show examples of images (one-frame images in moving images) based on image data from the camera 12 acquired by the image acquisition unit 251 of the control device 21. FIG. be.

Objects O11 and O12 are shown in image P1 in FIG. 6A. If the objects O11 and O12 are not shown in the image of the previous frame of this image, or if they are shown in the image of the previous frame but their positions in the image are different from that of the image P1, the detection unit 253 detects the objects O11 and O12. O11 and O12 are determined to be bird and animal image candidates.

Similarly, an object O2 is shown in the image P2 of FIG. 7(A). If the object O2 is not shown in the image of the previous frame of this image, or if it is shown in the image of the previous frame but the position in the image is different from that of the image P2, the detection unit 253 detects the object O2. It is determined that the image is a bird and beast image candidate.

Assume that the detection unit 253 refers to the database stored in the storage unit 257 to identify the images of the objects O11 and O12 in FIG. 6A as crows, and that the crows are harmful birds and animals. . In this case, the image generation unit 254 and the sound generation unit 255 identify animals that are natural enemies of crows from the database stored in the storage unit 257 . Suppose that the crow's natural enemy is identified as the hawk.

The image generation unit 254 reads the image data of the hawk from the database of the storage unit 257 and generates a moving image. The sound generation unit 255 reads the sound data of the hawk from the database of the storage unit 257 and generates the sound of the cry of the hawk. Then, the generated moving image data and audio data are output to the display device 11 and the speaker 13 via the output control unit 256, respectively.

FIG. 6B shows a state in which the display device 11 of the wildlife countermeasure device 1 displays a moving image N1 of a falcon. A moving image N1 of a hawk is displayed on the display device 11 . Under the control of the output control unit 256, the speaker 13 outputs a sound representing the cry of a hawk in cooperation with the moving image N1.

The crows B11 and B12 present near the display device 11 visually recognize the moving image N1 showing the figure of the falcon, which is their natural enemy, or hear the sound emitted by the falcon, and take actions to avoid them. . That is, the user leaves the place where the display device 11 is located. For example, when the wildlife countermeasure device 1 is installed on the steel tower 31 shown in FIG.

Similarly, for the image P2 in FIG. 7A, the detection unit 253 refers to the database stored in the storage unit 257, whereby the object O2 is specified as a monkey, and the monkey is a harmful bird or animal. Suppose it is judged. Then, it is assumed that the image generation unit 254 and the sound generation unit 255 have specified dogs as natural enemies of monkeys from the database stored in the storage unit 257 .

The image generation unit 254 reads the dog image data from the database stored in the storage unit 257 and generates a moving image. The voice generation unit 255 reads the voice data of the dog from the database of the storage unit 257 and generates the voice of the bark of the dog. Then, the generated moving image data and audio data are output to the display device 11 and the speaker 13 via the output control unit 256, respectively.

FIG. 7B shows a state in which a moving image N2 of a dog is displayed on the display device 11 of the wildlife protection device 1. FIG. Under the control of the output control unit 256, the sound indicating the barking of the dog is output from the speaker 13 in cooperation with the moving image N2.

A monkey B2 present in the vicinity of the display device 11 visually recognizes a moving image N2 showing a natural enemy dog, or hears the bark of the dog, and takes actions to avoid them. That is, the user leaves the place where the display device 11 is located.

According to the wildlife countermeasure device 1 of the present embodiment, an image and/or sound suitable for repelling the detected wildlife is generated.

In addition, when the wildlife is not detected, when it is not harmful even if it is detected, or when it is determined that the wildlife is no longer detected after being detected and the wildlife has retreated, the display by the display device 11 and the sound by the speaker 13 are performed. Since no output is performed, useless operation of the wildlife countermeasure device 1 can be suppressed.

It is also possible to obtain only one of them to detect birds and animals and specify the type of birds and animals.

(2) In the above-described embodiment, the display device 11 displays images of animals that are natural enemies of birds and animals, and the speaker 13 outputs sounds emitted by animals that are natural enemies of birds and animals. Audio may not be output. In this case, the speaker 13 does not have to be installed.

(3) In the above-described embodiment, an image of an animal that is a natural enemy of a bird or animal is displayed on the display device 11 as an image that the specified bird or animal avoids. It is also possible to display an image with a hue that is repelled by birds and animals. For example, an image of an object or an image of a luminous body in a color disliked by birds and animals may be output.

In addition, the display device 11 displays an image of an animal that is a natural enemy of a bird or animal as an image that the specified bird or animal avoids. may be For example, crows dislike white light with high emission intensity, so displaying such an image is effective.

The hues that birds and animals avoid may be stored by providing items in the data records of each of the birds and animals in the database stored in the storage unit 257 . The image generation unit 254 can read out the information on the hue that birds and animals avoid from the storage unit 257 , generate an image based on the information, and output the image data to the display device 11 via the output control unit 256 .

Information indicating that an image with varying luminescence intensity is to be avoided may be stored in the data record of each bird or animal in the database stored in the storage unit 257 by providing an item. The image generation unit 254 reads out from the storage unit 257 the information that birds and beasts avoid an image in which the emission intensity changes, generates an image based on the information, and causes the display device 11 to output the image data via the output control unit 256 . be able to.

Further, the image generating section 254 may generate an image combining an image of a hue that is repelled by birds and an image of varying light emission intensity that is repelled by birds and animals, and output the image to the display device 11 .

(4) In the above-described embodiment, the speaker 13 outputs sounds emitted by natural enemies of birds and beasts as sounds to be avoided by the specified birds and beasts. It is also possible to output a sound with a frequency that is repelled by birds or animals, or a sound whose frequency changes with time.

Moreover, it is also possible to output a sound whose volume changes with time so as to be avoided by the identified birds and animals. Further, it is also possible to output a sound having a frequency that the specified birds and animals avoid, and a sound whose frequency changes in a fluctuating cycle.

(7) In the above-described embodiment, a steel tower was exemplified as an installation location of the wildlife countermeasure device 1, but it may be installed in another location as long as it is likely to be damaged by wildlife. For example, installation in agricultural land such as fields and garbage collection sites is conceivable.

(8) In the above-described embodiment, the display device 11 displays an image of an animal, which is a natural enemy of birds and beasts. FIG. 9 is a diagram showing a display example of an image by the display device 11 of the wildlife protection device 1 according to the modification. 9, illustration of the camera 12, the speaker 13, and the microphone 14 is omitted.

As shown in FIG. 9(A), the wildlife countermeasure device 1 is installed on the ground such as a field. Specifically, the frame 111 of the display device 11 is installed in a state of being attached to a display device support portion 119 installed on the ground. The display device 11 is installed facing the aisle side through which people pass. That is, it is installed so that a passerby can visually recognize the displayed image. FIG. 9B shows a state in which an advertisement is displayed on the display device 11. FIG. In this state, a person H passing by can see the displayed advertisement.

Advertisement display can be performed by the following processing.
In the flowchart of FIG. 5, in steps S503 and S504, if birds and animals are not detected, or if they are detected but not harmful birds and animals, no image or sound is output (the process ends after steps S509 or S510). .

After that, the advertisement may be displayed until the processing from the next step S501 is started. The advertisement image data is stored in the storage unit 257 in advance. The output control unit 256 of the control device 21 reads the advertisement image data from the storage unit 257 and outputs the image data to the display device 11 . Then, as shown in FIG. 9B, an advertisement image is displayed on the display device. The advertisement image may be a moving image or a still image.

Also, the sound may be output from the speaker 13 in cooperation with the display of the advertisement. Advertisement voice data is stored in storage unit 257 in advance. The output control unit 256 of the control device 21 reads the audio data of the advertisement from the storage unit 257 and outputs the audio data so as to cooperate with the image data output to the display device 11 .

Also, as described below, an advertisement may be displayed on the display device 11 when the presence of a person is detected.
In the flowchart of FIG. 5, after step S509 or S510, that is, after an image is displayed and audio is not output, the detection unit 253 detects the presence of a person based on the acquired image data. This detection can be performed by the detection unit 253 by comparing the image acquired this time from the camera 12 with the image acquired last time, in the same manner as the detection of birds and animals.

That is, in the wildlife detection processing performed in step S502, among the objects in the image, an image that is a wildlife image candidate (the image is determined to be non-wildlife or harmful by the processing in steps S503 and S504). It is only necessary to judge whether or not a human being is a human.

Determination as to whether or not a bird and animal image candidate is a human image can be made by storing human image data in advance in the storage unit 257, reading the data, and comparing the data. In addition, if a human feature such as walking on two legs can be identified from an image that is a candidate image of a bird or beast, it may be determined that the image is a human. Also, if a voice such as a person's speaking voice can be extracted from the acquired voice data, it may be determined that a person exists even if the person cannot be detected from the image data.

As described above, when the presence of a person is detected, the output control unit 256 of the control device 21 reads out the advertisement image data stored in the storage unit 257 in advance, and displays the display device 11 as described above. output image data to . Also, as in the case described above, sound may be output from the speaker 13 in conjunction with the display of the advertisement.

When the presence of a person is not detected, no advertisement is displayed and no sound is output. In addition, when displaying advertisements (and outputting audio of advertisements), continue until the next time wildlife is detected and it becomes necessary to output images (and audio) as a countermeasure against wildlife, or until the presence of people is no longer detected. good too.

(9) In the above-described embodiment, the display device 11 is configured to display an image only on the front side of the device itself (that is, a configuration in which the image can be viewed only from the front side). Alternatively, an image may be displayed.
